First find the rate of growth
45000=18000(1+r)^(2010-2005)
Solve for r
r=((45,000÷18,000)^(1÷5)−1)×100
R=20%
Use it to find the population in 2015
P=45000(1+0.20)^(2015-2010)
P==111,974.4
The expression would be (5*6)+(5*6)=x
or you could shorten it and do (10*6)=x
9. 2.86600.... that is all i know so far
It could be B but I want to say D because it relates more to the question.
